Engine (2.5L/3.0L): Other Jaguar S-type I рестайлинг

Variable Intake System (V.I.S).

The variable intake system consists of a three stage upper intake manifold assembly, two position electronically driven gate valves and an engine management powertrain control system.

The engine control module (ECM) switches the intake manifold tuning valves between fully open and fully closed at calibrated engine speeds.

The intake manifold efficiency is therefore increased which will also increase the engine torque and engine performance.

Variable Camshaft Timing (VCT)

Oil is supplied to the front of each VCT actuator via the spider bracket assembly which contains the VCT actuator solenoid, supply oil galleries and timing chain guide. Oil pressure advances and retards the camshaft timing which is controlled by the engine management system via a solenoid valve mounted on top of the oil feed spider assembly. Camshaft timing, dependent on engine speed, load and oil temperature can be optimized over the adjustment range of 30 degrees.

Oil Pump

The rotary oil pump develops the oil pressure

1. The oil pump is located at the front of the crankshaft.
2. The oil pump is driven by the crankshaft.
3. A full flow oil filter is externally mounted on the oil filter housing.

If the filter element should become blocked a spring-loaded bypass valve will open and allow an uninterrupted flow of oil to the engine.
